To be correct, the rights belong to Infogrames Interactive = former Hasbro Interactive, now Atari Interactive and true owner of the Atari namerights, I guess now a subsidiary of Atari, Inc.

The auction is about Atari, Inc. = former GT Interactive

That one is also seperated from Atari SA = former Infogrames Entertainment SA, the original Fench Infogrames. Maybe you've heard from the IP transactions of Outcast, Silver and Desperados? These IPs belonged to Atari SA and not to Atari, Inc.
